The Corner Group Tool attaches to the mainframe of the B&D Multi Handler. This attachment serves as a 3-in-1 tool through the use of various adapter attachments to install and remove either the haul truck’s entire front corner group (spindle/brake assembly and front suspension cylinder) as one complete unit or the spindle/brake assembly and the front suspension cylinder split from each other as two separate units. Hydraulic cylinder motion is controlled with the B&D Multi Handler wireless radio remote controller.
